Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 1

Original Legal Text

1. A method comprising the following steps performed by a mobile terminal: receiving a control channel signal from a base station, wherein the control channel signal comprises a Modulation and Coding Scheme (MCS) Index, information on resource blocks used for a transmission from the mobile terminal to the base station, and a channel quality information trigger for triggering a transmission of an aperiodic channel quality information report to the base station, in case when the channel quality information trigger is set and the control channel signal indicates a determined value of the MCS Index and also indicates a number of resource blocks that is smaller than or equal to a determined number of resource blocks, transmitting the aperiodic channel quality information report to the base station without multiplexing the aperiodic channel quality information report, with protocol data unit(s) to be transmitted by the mobile terminal via an Uplink Shared Channel (UL-SCH), and in case (a) when the channel quality information trigger is set and the control channel signal does not indicate the determined value of the MCS Index, or in case (b) when the channel quality information trigger is set and the control channel signal does not indicate a number of resource blocks that is smaller than or equal to the determined number of resource blocks, transmitting the aperiodic channel quality information report to the base station while multiplexing the aperiodic channel quality information report with protocol data unit(s) to be transmitted by the mobile terminal via the UL-SCH.

Plain English Translation

A mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH).

Claim 2

Original Legal Text

2. The method according to claim 1 , wherein the determined MCS Index has value 29.

Plain English Translation

This is based on the method described where a mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH). Specifically, the predetermined MCS Index value that triggers separate CQI reporting is 29.

Claim 3

Original Legal Text

3. The method according to claim 1 , wherein the mobile terminal is configured to feed back the aperiodic channel quality information report on a Physical Uplink Shared Channel (PUSCH) based on one of a plurality of reporting modes.

Plain English Translation

This is based on the method described where a mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH). The CQI report is sent using the Physical Uplink Shared Channel (PUSCH), according to one of several possible reporting modes.

Claim 4

Original Legal Text

4. The method according to claim 1 , wherein a Physical Uplink Shared CHannel (PUSCH) is used to transmit the aperiodic channel quality information report.

Plain English Translation

This is based on the method described where a mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH). The CQI report is transmitted on the Physical Uplink Shared Channel (PUSCH).

Claim 5

Original Legal Text

5. The method according to claim 1 , wherein the channel quality information trigger is a Channel Quality information request bit.

Plain English Translation

This is based on the method described where a mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH). The channel quality information (CQI) trigger is specifically a single bit called the Channel Quality Information Request bit.

Claim 6

Original Legal Text

6. The method according to claim 1 , wherein the determined MCS Index indicates a redundancy version with value 1.

Plain English Translation

This is based on the method described where a mobile phone receives a control signal from a cell tower. This signal contains information including a Modulation and Coding Scheme (MCS) Index, resource block allocation for data transmission from the phone to the tower, and a channel quality information (CQI) trigger. If the CQI trigger is activated, the phone sends a CQI report to the tower. The way the CQI is reported depends on the MCS index and resource block allocation: if the MCS index has a specific predetermined value, and the allocated resource blocks are fewer than a predetermined threshold, then the CQI report is sent *separately* from normal data. Otherwise, the CQI report is sent *together* with regular data on the Uplink Shared Channel (UL-SCH). The predetermined MCS Index that triggers separate CQI reporting indicates a redundancy version with value 1.

Claim 7
